python - 在 Django 管理中添加和更改 View 的不同表单字段

Question

我想在 Django 管理中显示不同的表单字段以添加和更改 View 。

如果是add，那么我会显示表单字段file_upload，如果是change，那么我会显示模型字段 cname 和 mname

来自 admin.py 的代码

class couplingAdmin(admin.ModelAdmin):
    list_display = ('cname','mname')
    form = CouplingUploadForm #upload_file is here

    def get_form(self, request, obj=None, **kwargs):
        # Proper kwargs are form, fields, exclude, formfield_callback
        if obj: # obj is not None, so this is a change page
            kwargs['exclude'] = ['upload_file',]
        else: # obj is None, so this is an add page
            kwargs['exclude'] = ['cname','mname',]
        return super(couplingAdmin, self).get_form(request, obj, **kwargs)

如果是 add 就没问题，但如果是 change View ，那么我将获取所有字段，即 cname、mname、upload_file。

请建议我如何从管理员的更改 View 中删除 upload_file。

非常感谢任何帮助。提前致谢。

您可以覆盖 add_view和 change_view ModelAdmin 中的方法:

class CouplingAdmin(admin.ModelAdmin):
    list_display = ('cname', 'mname')
    form = CouplingUploadForm  # upload_file is here

    def add_view(self, request, extra_content=None):
        self.exclude = ('cname', 'mname')
        return super(CouplingAdmin, self).add_view(request)

    def change_view(self, request, object_id, extra_content=None):
        self.exclude = ('upload_file',)
        return super(CouplingAdmin, self).change_view(request, object_id)
